However, with long-term use, the roadbed at the roots of some old utility poles has become loose, and there is a safety hazard of collapse of the utility poles. The pole body reinforcement device of the cement utility pole is a device used to reinforce and position the cement utility pole. It is widely used in the installation occasions of cement utility poles and has a good use effect. The existing pole body reinforcement device of the cement utility pole cannot meet people's needs, so a more convenient pole body reinforcement device of the cement utility pole is needed. The existing pole body reinforcement device of the cement utility pole has certain disadvantages when used. First, a single clamp fixing structure is used, which is not firm enough to reinforce the cement utility pole, resulting in poor anti-dumping ability of the cement utility pole. Secondly, the ground adhesion is not high enough, which reduces the fixing strength of the device. For this reason, we propose a pole body reinforcement device for the cement utility pole.

DETAILED DESCRIPTION
[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0015] like Figure 1 The bottom reinforcement and correction structure of a utility pole shown in the figure includes a fixing kit and a supporting assembly. The fixing kit is sleeved on the middle and lower part of the utility pole. The fixing kit is a tubular structure. The tubular structure generally adopts several specifications and sizes and is suitable for utility poles of various diameters. There may be a gap between the tubular structure and the utility pole.
[0016] The tubular structure is divided into a first set 1 and a second set 2, both of which are arc-shaped plate structures. Screw holes 3 are provided on both side edges of the first set 1 and the second set 2. The screw holes 3 of the first set 1 and the screw holes 3 of the second set 2 are connected by screw rods 4. Specifically, two screw holes 3 are provided on one side edge of the first set 1 and the second set 2. The screw holes 3 are hingedly arranged with the first set 1 or the second set 2. After the first set 1 and the second set 2 are placed at a suitable height, the two screw holes 3 at the corresponding positions of the first set 1 and the second set 2 are connected and fixed by screw rods 4.
[0017] Two lower pressure plates 5 are respectively provided on the outer walls of the first set 1 and the second set 2, and the lower part of the lower pressure plate 5 is provided with an internal threaded tube 6 and an external threaded rod 7 that cooperate with each other, and the external threaded rod 7 is partially placed in the internal threaded tube 6, and the bottom end of the external threaded rod 7 is a supporting plane 8. Specifically, an upper groove 11 is provided above the lower pressure plate 5 of the first set 1 or the second set 2, and a lower groove 12 is provided at the end of the lower pressure plate 5 away from the first set 1 or the second set 2, and a support rod 13 is provided between the upper groove 11 and the lower groove 12; after adjusting the extended length of the internal threaded tube 6 and the external threaded rod 7, the reaction force is applied by the support rod 13, which can increase the pressure of the supporting plane 8 on the ground, reduce the force on the root of the electric pole, and disperse it on each supporting plane 8, and the length between the internal threaded tube 6 and the external threaded rod 7 can also be adjusted to correct the upright condition of the electric pole.
[0018] A plurality of winding holes 9 are provided around the lower part of the externally threaded rod 7, and a steel wire rope 10 is continuously wound between the winding holes 9 of the four externally threaded rods 7. In order to prevent a certain supporting plane 8 from sliding on the ground and to prevent a certain internally threaded tube 6 from rotating relative to the externally threaded rod 7, thereby affecting the extended length, the steel wire rope 10 is connected together on the four internally threaded tubes 6, specifically, connected on the winding holes 9 on the inner side of the internally threaded tube 6, so as to prevent the internally threaded tube 6 from rotating and the internally threaded tube 6 from being displaced, thereby ensuring the stability of the electric pole.
[0019] A fixed sealing ring 14 is provided at the bottom of the fixing kit composed of the first kit 1 and the second kit 2, and a gap is provided between the fixing kit and the electric pole, in which cement is cast, and expansion screws 15 embedded in the dried cement are set on the first kit 1 and the second kit 2; as one of the improvements of the present invention, in order to improve the connection degree between the fixing kit and the electric pole, the connection is made in the form of cement to ensure that the cement and the electric pole form a whole, and then the expansion screws are driven into the cement part to make the fixing kit and the electric pole form a whole, so that under the action of the support rod 13, the internal threaded tube 6 and the external threaded rod 7, the fixing kit will not be separated from the electric pole, and such a modification will not damage the pole body of the electric pole, and will not change its original structure, thereby avoiding breakage and cracking and affecting use.
[0020] Typically, the four lower pressing plates 5 on the outer walls of the first set 1 and the second set 2 are arranged equidistantly in pairs; the external threaded rod 7 and the supporting plane 8 are rotationally connected.
[0021] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
